WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 567,370, dated September 8, 1896.

Application filed January 23, 1896. Serial No. 576,615. (No model.)

To all whom it flea/y concern.-

Be it known that I, PAUL H. BAUKOL, a citizen of the United States, residing at Grand Forks, in the county of Grand Forks and State of North Dakota, have invented certain new and useful Improvements inWin dow- Screens and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in window-screens of that class or construction which is intended to permit flies or other insects to crawl from the inside out through an aperture, but which prevents them from finding entrance to the inside; and the object is to construct a screen for the purposes mentioned which will serve all that is intended and which is durable in parts, easily and cheaply made, and sightly in appearance.

I attain the purposes of my invention'by means of the construction of parts and their the drawings.

assemblage in a common constructionwhich I have illustrated in the accompanying drawings, forming a part of this specification, and wherein- Figure 1 is a view in perspective taken from the outer side of the screen and showing the complete device. Fig. 2 is a vertical section taken on a line adjacent to the left-hand stile of Fig. 1. Fig. 3 is a detail of one of the inclined side pieces of the screen-frame. Fig. 4 is a detail View of a portion of the angular rail or bar. Fig. 5 is a View showing the spreader and the blank from which it is constructed.

Referring to the drawings, A designates a suitable frame to which the screen or screens are connected or secured. This frame may be of any size suited to the window or door to which it is fitted, and consists of the side pieces or stiles 1 2 and top and bottom rails 3 4. To the stiles are secured side pieces 5 5 and 6 6 of similar construction, having their outer faces inclined, as seen at 7, fromtop to bottom, and formed with seats 8 at their upper ends, in which the ends of the angular crossbars are arranged and secured.

B designates the lower section of the screen, composed of a suitable wire-netting, the upper end of which is turned about and secured on a metal cross-bar 9, substantially as shown in This section B of the screen is laid on the inclined side pieces 5 5 and sec ured in position by means of cleats or strips 10 10 fastened by nails or screws.

0 designates a section of the screen made of wire-netting, and having at its lower end a metal cross-bar 1'1, bent at a suitable angle in cross-section, substantially as shown, the screen bein g turned up and partially down on itself to a distance substantially the width of the crossbar. At the top of the screen-section 0 is also a cross-bar 12, about which that end of the screen is folded and secured. This section is placed in position by laying it on the side pieces 6 6 with its turned-up lower end 13 in the seats in the top of the nearest lower side pieces 5 5 and 6 6 as seen in Fig. 2 of the drawings, and then fastening on the cleats or strips 14514 over the edges of the wire-netting, the lower ends of the cleats be ing pushed down tight into the seats, with the netting and cross-piece about them, as seen in the drawings. This arrangement and disposition of the adj acently r disposed overlapped ends of the upper and lower ends of the screens form an opening between them having substantially parallel inclined surfaces, so that a fly or other insect crawling up the screen will continue its travels through the opening and land on the outside of the screen.

At the upper end of the upper section is secured a short strip of netting 15, closing the upper part of the opening in the frame, and is provided in its lower end with an angular crossbar 16, and having the end turned up and arranged in the seats formed in the upper ends of the upper side pieces 6 6 and secured therein by meansof short strips or cleats 17 17 having the ends pushed snugly down in the bend of the netting, substantially as shown. This arrangement of the parts affords the upper opening of the screen, through which the insects find exit into the outer air. To prevent the adj acently-arranged crossbars from being bent or displaced, I arrange a bracing piece or plug 18betweenjthem, as shown. This brace or pluglS is madeout of a piece of sheet metal cut into the shape of a cross, and then striking down the two shorter arms parallel with each other to adapt them to be inserted between the meeting rails and bending the other arms to lie over and against the opposite faces of the two rails or crossbars, substantially as shown in the drawings.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A window-screen, comprising a suitable rectangular frame, side pieces secured to the stiles of the frame, having their outer faces inclined from top to bottom and formed with seats in their upper ends, a wire-netting having a cross-bar in its upper end secured on the lower inclined side pieces, wire-nettings secured to the inclined side pieces, each having a metal cross-bar secured to its upper end and a metal cross-bar bent angular in crosssection, secured to its lower end and disposed and secured in the seats in the upper ends of the nearest lower side pieces, and a short section of netting to close the upper end of the frame, provided with a cross-bar angular in cross-section disposed in the seats in the upper ends of the upper side pieces, substantially as and for the purposes specified.

2. A window-screen, comprising a suitable frame, side pieces secured to the stiles of the frame, having their outer faces inclined from top to bottom and formed with seats in their upper ends, a wire-netting having a metal cross-bar in its upper end, secured to the lower inclined side pieces, a wire-netting secured to the inclined side pieces and having a metal crossbar in its upper end, and its lower end turned up and bent over and a metal cross-bar angular in cross-section secured in the bent-up portion, which cross-bar and bent-up portion are disposed in the seats in the ends of the nearest lower side pieces, a short section of wire-netting to close the upper end of the frame, a cross-bar angular in cross-section on the lower end of the short screen-section and disposed in the seats of the PAUL ll.
